How do house alarms work?

While there are many different types of house alarm systems (including wired, wireless, ap-controlled, and policed systems) that communicate in various ways, they tend to detect the presence of intruders using the same method – motion sensors.

Put simply, a motion sensor is a device that detects the movement of objects in its surroundings by sending out energy (in the form of light, microwaves, or sound) and analysing the reflected pattern for changes. If it detects changes (and movement by someone or something has disturbed the pattern), it will send a signal to the house alarm control box.

What can trigger an intruder alarm?

The most obvious trigger for an intruder alarm is, of course, movement. However, intruder alarms can also be triggered unintentionally by a long list of factors such as human error, pets, lack of maintenance, loose connections, low batteries, excessive dust, as well as loose sensors and detectors.

Intruder alarms can also be set off by having an unreliable power source alongside unlocked or loose windows and doors. As door and window motion sensors are designed to detect movement in these areas, any rattling or accidental opening can disrupt the sensor connection and trigger the house alarm.

Regular house alarm maintenance is therefore essential if you want to limit the frequency of false alarms and enjoy peace of mind in your home or business premises. On top of this, you should also ensure key entry points that are being monitored by your alarm system are secure when closed or locked.
